Now I’m not only getting this “Download failed. Not Found” error when upgrading plugins, but when trying to install new plugins. This is really hindering my production since I can’t upgrade or install plugins due to this problem.
I have one hunch I want to follow up on…maybe it is related to the zip file name having “zipname.5.4.3.2.1.zip or some crazy thing like that for file versioning.
Here’s an example:
Downloading update from https://downloads.www.ads-software.com/plugin/add-to-any.0.9.9.6.9.zip…
Download failed. Not Found
Can anyone confirm this with some testing by downloading and renaming the zip file before upgrading?
I.E. download plugin, rename zip file, de-activate existing plugin, delete existing plugin, upload new/upgraded plugin zip file.
Of course this would be a pain if we had to do this for every plugin upgrade. But if we could identify that this is the problem we can submit a bug report to WP team.
